You can usually save the router configuration.
@royI’ve just returned from testing the box at a friend’s house and it worked perfectly. It did update the software so I was hopeful that it might work when I got home. Unfortunately it doesn’t but at least I’m not restricted to the set up screen. It still tells me it can’t connect to the internet and quotes YVM104. I seem to have access to settings so is there anything else I can try from here?My friend uses BT so I wonder if that’s what allowed it to work?
